IPC: A23F3/06
Filed: 1995-02-21
Abstract: PURPOSE: To provide a structure for sampling and measuring the moisture content suitable for automatically and continuously determining the moisture content of raw green tea leaves. CONSTITUTION: This apparatus for sampling and measuring raw green tea leaves is obtained by installing, e.g. a device S for sampling the raw green tea leaves and measuring properties of the raw green tea leaves containing the moisture content of the raw green tea leaves A so as to take out a part of the raw green tea leaves A from a chute 3a of a vertical bucket conveyor 3 for the raw green tea leaves in installing the device S. The driving speed of a belt conveyor in a sampling and raw green tea leaf flow meter 20 for feeding the raw green tea leaves A to a moisture measuring device 30 is controlled based on the weight or transfer height of the raw green tea leaves A transferred through the moisture measuring device 30.  Thereby, the transferred raw green tea leaves can simply be taken out by a relatively inexpensive structure and the moisture content can accurately be measured without requiring an installation space and further a change in line of the existing green tea manufacturing line.

Title: Method for detecting destruction and fracture of rigid body
Inventor: OKAMOTO HIROYUKI
IPC: G01M99/00
Filed: 1982-04-06
Abstract: PURPOSE:To detect the destruction and fracture of the rigid body efficiently and accurately, by detecting the vibrating frequency generated at the time of the destruction and fracture by a crystal vibrating piece having a selected response frequency band. CONSTITUTION:A cut chip 2 to be detected is fixed to the tip part of a cutting tool body 1. The crystal vibrating piece 5 having the selected responce frequency band is resonated with a propagated vibrating wave 4 that is generated when the chip 2 is fractured or destructed. The crystal vibrating piece 5 is attached and fixed on the cutting tool body 1. In this way, the destruction and fracture of the rigid body 2 to be detected are detected by the crystal vibrating piece, which is resonated with only the vibrating frequency generated at the time. The response frequency band of the crystal vibrating piece can be made extremely small based on the natural frequency of the crystal itself. The vibration caused by the fracture and destruction of the chip can be selectively picked up.

Title: Production of pure water
Inventor: TANABE MADOKA
IPC: C02F1/469
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To efficiently remove hydrofluoric acid when a mixed acidic water containing hydrofluoric acid and mineral acids is treated with an electrically deionizing device, by adding an alkali to the mixed acidic water before the treatment until its pH value reaches a range where hydrofluoric acid is dissociated. SOLUTION: An alkaline solution is added to water to be treated, comprising a mixed acidic water of hydrofluoric acid and mineral acids, by a pH controller 1 before supplying the water to an electrically deionizing device (EDI device) 2. The water to be treated, after the pH adjustment, flows into the EDI device 2. The EDI device 2 has a desalination chamber, a concentration chamber, and a pair of electrodes. The water to be treated and concentrated water pass through the desalination and concentration chambers respectively. As the pH of the water to be treated has been adjusted within the range where hydrofluoric acid is dissociated to ions, fluorine ions are remove to the concentrated water which flows through an ion-exchange membrane.  Thereby the treated water from which hydrofluoric acid has been removed can be obtained, and concentrated water in which salts have been enriched can be obtained at the same time in the concentration chamber.
